Working Principle of X-Ray Machine – StudiousGuy
Generally, an x-ray machine consists of 10 blocks. The working of each block is given below: 1. High Voltage Source. The main purpose of using a high voltage source control to power an x-ray machine is to allow the proper operation of the x-ray tube. The voltage value typically ranges from 30 to 150 kilovolts (kV). 2.

The principle of operation of an RCD (residual current device)
The principle of operation of the RCD is based on the measurement method. At the input and output, the readings of the currents flowing through the transformer are recorded. If the input current reading is higher than the output, then there is a current leak somewhere in the circuit and the protective device is disabled.

Electric Machines
Principle of operation of synchronous machines Alternators. When DC voltage is applied to the rotor, it becomes an electromagnet. If the rotor is driven by a prime mover, a relative motion happens between the rotor magnetic flux and the stator conductor. Therefore according to faraday's law, an EMF is induced in the stator winding.
